The Scaled Agile Framework (SAFe) emphasizes that Lean-Agile Leaders are the key enablers of a Lean-Agile transformation. They are the ones who must lead by example, embodying the principles and values of SAFe and promoting a culture of lifelong learning. This is crucial because these leaders are responsible for driving the adoption of SAFe practices across the organization. They are expected to be continuous learners, always seeking to improve their understanding of Lean-Agile practices and principles, and to foster an environment where everyone is encouraged to learn and grow. The Release Train Engineer (RTE) role, while also being a servant leader and coach, primarily facilitates ART events and processes, and supports teams in delivering value. However, the emphasis on lifelong learning as a primary responsibility is specifically associated with Lean-Agile Leaders within the SAFe framework1.
